Ok, I found what is causing the problem but I don't understand why. Yet.
The root of the problem is the URL you have before the the images. Again, I don't know why this is causing a problem but I do know that when I moved the URL to after the images, the problem went away. This was confirmed with a test posting on the administrator forum. I'll be looking into this issue in more depth but I have a suspicion that's it's being caused by the code the generates the preview for recent messages.
